Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 84,725,071, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
1 | 84,725,071 | |
-1 | -84,725,071 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 84,725,071.
Example:
1 x 84,725,071 = 84,725,071
and
-1 x -84,725,071 = 84,725,071
Notice both answers equal 84,725,071
With that explanation out of the way, let's continue. Next, we take the number 84,725,071 and divide it by 2:
84,725,071 ÷ 2 = 42,362,535.5
If the quotient is a whole number, then 2 and 42,362,535.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 84,725,071 | |
-1 | -84,725,071 |
Now, we try dividing 84,725,071 by 3:
84,725,071 ÷ 3 = 28,241,690.3333
If the quotient is a whole number, then 3 and 28,241,690.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 84,725,071 | |
-1 | -84,725,071 |
Let's try dividing by 4:
84,725,071 ÷ 4 = 21,181,267.75
If the quotient is a whole number, then 4 and 21,181,267.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
1 | 84,725,071 | |
-1 | 84,725,071 |
If you did it right, you will end up with this table:
1 | 379 | 223,549 | 84,725,071 |
-1 | -379 | -223,549 | -84,725,071 |
